The posting

About the role:

Own the test that proves our AI accelerator hardware works — from the packaged units, to the boards they sit on, to the systems they ship in. You'll develop the test setups, test hardware, and coverage/yield/throughput that let us catch problems early and ship at volume. You'll sit at the seam between silicon/packaging and the systems our accelerators run in, and own the test strategy that spans package level, board level, and — increasingly — full system level.

What you'll do

  • Develop and run package-level test — socket-based bring-up and validation of packaged units: power-up, interface/interconnect continuity, and functional/parametric checks against spec (board↔package interface, not ATE silicon device test)
  • Develop and run board-level test — functional, structural (boundary scan/JTAG), in-circuit, and bring-up validation for accelerator boards and system hardware
  • Build out system-level test — bring up and validate assembled accelerator systems against spec, including functional, stress, and burn-in flows
  • Design and validate test hardware and fixtures — sockets, connectors, load boards, and board/system fixtures for high-speed and high-current test
  • Drive test coverage, yield analysis, and test-time/cost reduction across the product lifecycle
  • Lead new-product test bring-up; resolve test escapes, yield excursions, and hardware failures with data-driven root cause
  • Run characterization and correlation across levels — package ↔ board ↔ system, and bench ↔ production test
  • Define test specs, limits, and guardbands with design, product, packaging, and reliability engineering
  • Transfer and sustain test programs at OSAT/CM and manufacturing partners through ramp to high volume
  • Use and develop AI-assisted tool flows to accelerate test development, debug, and yield analysis

What we're looking for

  • BS/MS in Electrical/Computer Engineering or equivalent plus 5+ years in package/board/system-level hardware test engineering
  • Hands-on test experience across at least two of package-level, board-level, and system-level test — with the ability to own the others
  • Package and board test hardware experience (sockets, connectors, load boards, fixtures) and the signal/power integrity that comes with high-speed, high-current test
  • Lab bring-up and debug skills: oscilloscopes, logic and protocol analyzers, power and thermal instrumentation
  • Data analysis and statistical skills for yield, characterization, and correlation work
  • (Optional) High-speed I/O / SerDes, DDR/HBM, RF, or high-current/power-device test; structural test (boundary scan); scripting/automation (Python, C++); system burn-in and reliability test; OSAT/CM partner management

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
